1. 1. Well Testing, Methods and Applicability

   Författare :Jan-Erik Rosberg; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slug tests; well completion; re-injection; Well testing; pumping tests; injection tests; well development; pneumatic initiation; hydro-jetting; coiled tubing; tunnel lining; deep wells;

   Sammanfattning : Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. LÄS MER

3. 2. Hydro-Mechanical Behaviour of a Pressurised Single Fracture: An In-situ Experiment

   Författare :Patrik Alm; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydro-mechanical behaviour; hydraulic field test; transmissivity; effective stress; aperture; fracture stiffness; fracture; slug test;

   Sammanfattning : Exploration of ground water resources, grouting, disposal of nuclear waste and extraction of geothermal energy are examples of activities which require consideration of the relationship between effective stress and transmissivity. However, this relationship is poorly understood and very few investigations have been conducted in field scale. LÄS MER

4. 3. A multi-scale approach for predicting the fire response of building barriers

   Författare :Blanca Andrés Valiente; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Building Barriers; Heat transfer; Experimental; Gypsum; Stone wool; furnace; H-TRIS;

   Sammanfattning : Building barriers are compartmentation elements in buildings that limit the passage of fire and smoke to adjacent spaces. They are key elements in the overall response of a building in a fire. The adequate fire response of building barriers is usually assessed by the fulfilment of standardized resistance to fire tests.

5. 4. On the applicability of geophysics for groundwater investigations in areas with lack of hydrogeological information. Examples from Mozambique

   Författare :Farisse Joao Chirindja; Teknisk geologi; []
   Nyckelord :Mozambique; Geophysics; Reference data; Hydrogeology; Groundwater;

   Sammanfattning : The work presented in this thesis has aimed to improve the knowledge about the groundwater occurrence in different geological conditions in Mozambique. The main focus in this study has been on the understanding of hydrogeological conditions in area with little background information by use of geophysical investigation. LÄS MER

7. 5. Flow Boiling Heat Transfer in Single Vertical Channels of Small Diameter

   Författare :Claudi Martin Callizo; Björn Palm; Predrag Hrnjak; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microchannel; heat exchanger; heat transfer; flow boiling; flow patterns; onset of nucleate boiling; dryout; critical heat flux; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

   Sammanfattning : Microchannel heat exchangers present many advantages, such as reduced size, high thermal efficiency and low fluid inventory; and are increasingly being used for heat transfer in a wide variety of applications including heat pumps, automotive air conditioners and for cooling of electronics.However, the fundamentals of fluid flow and heat transfer in microscalegeometries are not yet fully understood.
